Glass manufacturing

Industrial gas supply and technology in glass manufacturing industry

Production of more transparent and pure glass products

Glass manufacturing has a history of more than 5,000 years, but just 20 years ago, Praxair took a leap forward in this traditional process into the 21st century. With a range of industrial gases, technologies and equipment, we have successfully turned bottle and glass furnaces into oxyfuel burners. This is not only good news for customers, but also good for our planet. Oxygen fuel melting improves the quality of glass products. In addition, it requires less fuel and has higher combustion efficiency, saving costs for customers. It also significantly reduces nitrogen oxide emissions and helps you meet current regulatory requirements. Glass products made with our burners are more transparent and more productive.

Industrial gases for glass manufacturing, production and furnace industries

OxygenOxygen rollover oxygen

Oxygen is an industrial gas that improves production efficiency and can be used to enhance glass furnace combustion and reduce nitrogen oxide emissions.

NitrogenNitrogen rollover Nitrogen

Nitrogen is used to inert glass during the manufacturing process. This process prevents oxidation and allows the furnace to cool down.

HydrogenHydrogen rollover hydrogen

In the manufacture of float glass, hydrogen and other industrial gases can reduce the gas in the upper part of the tin bath to prevent oxidation.

HeliumHelium rollover Helium

Helium can be used as a coating to meet the high quality requirements of the industry. Coatings can reduce product defects and increase equipment life.

Industrial applications in glass manufacturing, production and processing industries

Aerated combustion

Praxair's Lean Oxygen Combustion (DOC) technology for glass melting injects fuel and oxygen through separate combustion ports. This industrial application eliminates most of the nitrogen in the combustion air, reduces nitrogen oxide emissions by 90%, saves fuel costs and improves production efficiency.

Oxygen Enhanced Combustion Glass

Industrial products for the glass manufacturing, production and furnace industry

DOC Wide Flame Burner

Lean oxygen combustion-wide flame burner

Oxy-fuel burners feature wide flames, low nitrogen oxide emissions, and low maintenance. The flame has high brightness and small fire potential, which can make the heat transfer during the melting process reach the optimal state and prevent the overheating zone from appearing.

OPTIFIRE JL burner

Lean oxygen combustion – JL burner

Suitable for large area, lean oxygen combustion-JL burner is based on innovative lean oxygen combustion technology, which reduces the emissions of glass furnaces.

DOC Forehearth Burner

Lean oxygen combustion-forehearth burner

It can save a lot of fuel in the front furnace of glass melting furnace. Praxair front furnace burner greatly improves the uniformity of glass melting temperature.
